Work out whether slowdowns affect the whole connection or just particular rooms before buying Wi-Fi equipment: Ofcom notes that Wi-Fi cannot outperform the underlying broadband service. Consider direct Ethernet for a fixed work or gaming device, and mesh or a targeted access point for persistent coverage gaps. Replace the main router only after checking your provider’s connection requirements; if several devices slow down even close to the router, check the broadband options for your address.
Calls or streams work near the router but become unreliable farther away, upstairs or behind substantial internal walls. The purchasing question is whether better placement is enough or wider wireless coverage is needed.
A work computer or games console stays in one place, and a dependable connection matters more for that device than wireless mobility. Ofcom advises that a computer connected directly to the router by Ethernet should have a faster, more reliable connection than over Wi-Fi.
The current router appears unreliable or no longer meets the household’s needs, but a replacement must match the broadband access type and the provider’s connection requirements.
Compare the connection near the router with the rooms and devices having trouble. That distinction helps you decide whether to address coverage, wire one device, check router compatibility or investigate the broadband service.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Coverage gaps | Try a better router position first. If weak spots remain, consider the rooms, floors and possible locations for mesh nodes or an access point. | If calls work near the router but fail in an upstairs room, I need coverage in that room rather than a change to the incoming service; around 30% of consumers would put coverage first. |
| Fixed-device reliability | Check for an Ethernet port or compatible adapter, an available router port and a practical, safe cable route. | When my desk computer needs a dependable connection during other household activity, I would rather wire that device than depend on its Wi-Fi signal; roughly 30% of consumers would make fixed-device reliability their primary concern. |
| Router compatibility | Match the replacement router’s connection features to the exact provider and broadband access type before purchase. | If I am replacing a provider-supplied router, I need the new one to connect to my particular service and accept the setup involved; around 20% of consumers would prioritise router compatibility. |
| Broadband capacity | Compare performance close to the router and, where practical, over Ethernet; check service availability at the specific address. | If several people slow down at once even beside the router, I need to know whether the broadband service is the constraint before buying Wi-Fi hardware; about 20% of consumers would put service capacity first. |
New wireless equipment cannot raise the performance of the incoming service. Ofcom advises that Wi-Fi cannot outperform broadband, so slowdowns across the home during simultaneous use need a different check from a weak signal in one room.
Compare use near the router and, where practical, through a direct Ethernet connection. If the problem persists, check broadband availability for the exact property before choosing mesh or a new router.
Connection requirements differ by provider and access type. EE’s guidance, for example, distinguishes between FTTP, FTTC/SOGEA and ADSL/SOADSL connections; a router missing a required connection feature may not get online.
Ask your provider which authentication method, WAN or modem features and settings your service requires. Keep the supplied equipment available until the replacement has been connected and tested.
Setting up third-party equipment may take more work, and provider help with that router may be limited.
Mesh addresses wireless coverage around the home. If the main concern is one computer at a fixed desk, it may not address that device’s need as directly as a cable to the router.
Assess a safe direct Ethernet route for the fixed device. Consider mesh if phones, laptops or other wireless devices also struggle in separate rooms.
Ofcom notes that building materials can affect Wi-Fi, while larger homes may need more mesh units. A quoted coverage area does not tell you where units can be placed in your home.
Identify the rooms that need a connection and check the manufacturer’s placement guidance for the particular system.
Additional units may be needed if walls, floors or practical placement prevent useful coverage.
Compare the particular range and model with the connection problem you are trying to solve; a brand name alone does not establish coverage or compatibility.
TP-Link’s Deco range covers whole-home mesh systems with different configurations.
eero offers home mesh systems with app-led setup and network management.
NETGEAR’s Orbi range includes multi-unit mesh systems for whole-home coverage.
Ubiquiti’s UniFi range is relevant to households considering wired access points and more configurable networks.
This range-extender choice is relevant when one area needs better Wi-Fi and the existing router’s signal can still reach a suitable extender position. It is not a replacement for a direct Ethernet run or for checking a broadband-service bottleneck.

Consider this range extender for a weak-signal area where it can still be positioned within range of the existing router.
Yes, if its current position may be weakening the signal. Ofcom advises checking placement; if broadband works well near the router but separate rooms still have weak Wi-Fi after repositioning, a mesh system may address the coverage gap.
No. Mesh can address Wi-Fi coverage inside the home, but Ofcom notes that Wi-Fi cannot outperform the underlying broadband service. If use is poor even close to the router or over Ethernet, investigate the service before buying mesh.
Confirm your provider, access type and the connection features required for that specific service. EE’s guidance, for example, calls for PPPoE support and sets different hardware requirements for FTTP, FTTC/SOGEA and ADSL/SOADSL; another provider’s requirements may differ.
Do not assume it will. Ofcom cautions that a non-provider router can be harder to set up and that provider help may be limited; EE says it does not support third-party-router setup or troubleshooting. Check your provider’s support arrangements before replacing its equipment.
